Chatham House Rule

The Chatham House Rule is a system for holding debates and discussion panels on controversial issues, named after the headquarters of the UK Royal Institute of International Affairs, based in Chatham House, London, where the rule originated in June 1927.


At a meeting held under the Chatham House Rule, anyone who comes to the meeting is free to use information from the discussion, but is not allowed to reveal who made any comment. It is designed to increase openness of discussion.

The Rule

The Rule was created in 1927 and refined in 1992. Since its most recent refinement in 2002, the rule states:

When a meeting, or part thereof, is held under the Chatham House Rule, participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s), nor that of any other participant, may be revealed.

Sometimes the reference is made to Chatham House rules, plural. However Chatham House clearly states that there is only one rule, hence it should not be used in the plural.


The rule is designed to increase openness of discussion of public policy and current affairs, as it allows people to express and discuss controversial opinions and arguments without suffering the risk of dismissal from their job, and with a clear separation from the opinion and the view of their employer.

The rule allows people to speak as individuals and to express views that may not be those of their organisations, and therefore encourages free discussion. Speakers are free to voice their own opinions, without concern for their personal reputation or their official duties and affiliations. The Chatham House Rule resolves a boundary problem faced by many communities of practice, in that it permits acknowledgement of the community or conversation, while protecting the freedom of interaction that is necessary for the community to carry out its conversations. It is designed to reduce the risk of what has come to be described as groupthink, where unpopular views are excluded from discussion, reducing the range of opinions an organisation can discuss.

The aim of the rule is to guarantee anonymity to those speaking within its walls so that better international relations may be achieved. The rule is now used internationally as an aid to free discussion. The original rule of 1927 was refined in October 1992 and again in 2002. Chatham House has translated the rule into Arabic, Chinese, French, German, Portuguese, Spanish and Russian.

The rule is a contrast (or a compromise) between private meetings, where revealing what was said in the meeting is forbidden, and on the record events where the discussion is completely public and attributed.

Generally, the Chatham House Rule is imposed as a condition of being allowed to attend a meeting or event: all participants are understood to have agreed that it would be conducive to free discussion that they should be subject to the rule for the relevant part of the meeting. The success of the rule may depend upon it being considered morally binding, particularly in circumstances where a failure to comply with the rule may not result in sanction.

Concern over ECB use

In May 2015, the release of a rule-bound speech by European Central Bank board member Benoît Cœuré triggered broader attention to the bank's use of the system. The Cœuré speech influenced currency, stock and bond markets. In the aftermath, other recent ECB invocations of the rule regarding a question-and-answer session and opening remarks for Cœuré, respectively, by ECB Vice President Vitor Constancio and another member of the board, Peter Praet, also gained attention. An ECB governing council member Boštjan Jazbec of Slovenia also had, the same month, held a Questions & Answers session under the rule.
